#4 - CADWGAN FANTACH
Although Bartrum had not yet discovered,
when he wrote his "Patriarchs" paper in 1963, that there were two men named Cadwgan Fantach who share a common ancestor, he
did present two separate pedigrees:
(1) "Kadwgon vantach ap Kadwgon ap
Llywelyn ap Gruffudd ap Ridid ap Edelvrych ap Peredur peiswerdd arglwydd Keredigion uchaf"
(2) "Kadwgon vantach o Lannddewi vrevi
ap Gruffudd ap Maredudd ap Einion ap Rhys ap Karedic ap Klodrydd ap Gwallter ap Pill ap Predyr peisswyn ior Karedigion"
In his notes, Bartrum said:
"Cadwgan Fantach of Llanddewi
Brefi, born c. 1200. The male line ended with his son Maredudd, who left three heiresses. See Dwnn i, 82, 94,
222, etc. [Pedigree (2)] seems to show confusion with [the pedigree for Rhys Chwith]"
When Bartrum published
his Welsh Genealogies AD 300-1400 in 1974, he charted separate men for his two pedigrees, both descended from a consolidated
Peredur Beiswrydd/Beisgwyn but from different sons of Peredur. There, he dated the Cadwgan Fantach who had the son Maredudd
to c. 1200, while he makes Cadwgan Fantach II born c. 1300 and the man who lived in Llanddewi Brefi in the commote of Pennardd.
We would date the earlier
Cadwgan Fantach (the toothless) to c. 1205 based on our analysis of the marriage matches cited for his son and granddaughters.
His son Maredudd married Gwenllian ferch Maredudd ap Owain ap Gruffudd ap Lord Rhys, a lady born c. 1240. The daughters
of Maredudd married men born form c. 1250 to c. 1260, so these ladies should be dated c. 1265/70. The pedigree (Bartrum's
#1) which he proposes for this Cadwgan Fantach is a generation too short (he dates Peredur 25 years earlier than our
estimate). Alternate pedigrees, which Bartrum mentioned, substitute the name Maredudd for Rhiryd as the grandson
of Peredur; we suggest both names belong in the pedigree although it is only a guess which of the two was the father of the
We propose the following chart:
995 Peredur Beisgwyn
1205 Cadwgan Fantach
1265/70 Three daughters
The man whom Bartrum
calls Cadwgan Fantach II is the one whose residence is cited as Llanddewi Brefi. We estimate his birthdate as c. 1310.
He lived near the Tregarron manor of the Clement family whose men were in the military service of the English Crown, and he
married a daughter of the Lord of Pennardd, Sir Robert Clement, son of the second Geoffrey Clement. While not
named in the sources, this lady was born c. 1325.
The Bartrum pedigree
(his #2) is a generation short as given. Other sources cite a "Ceredig ap Gwallter ap Pyll ap Peredur Beisgwyn",
so we would insert Ceredig between "Klodrydd" and "Gwallter" as:
995 Peredur Beisgwyn
1245 Maredudd Geoffrey Clement II 1265
1275 Gruffudd Sir Robert Clement 1293
1310 Cadwgan Fantach II====daughter 1325
In our analysis of Bartrum's
pedigree for the common ancestor of these men, we shall present our reasons for identifying him as Peredur Beisgwyn (not Beiswrydd)
and for dating his birth c. 995.
